14” Necklace - The smallest common necklace size for women is the 14” necklace. This size is going to fit almost as tight as a choker and is usually reserved for thinner style necklaces.

16” Necklace- The 16” necklace is going to have a chain that will rest around the base of a woman’s neck similar to a collar. For more petite women, this size will most likely fall at the collarbone while feeling similar to a choker for plus size women.
